Synchronization primitives built with [portable-atomic].
- Provide `Arc`. (optional, requires the `std` or `alloc` feature)
- Provide `task::Wake`. (optional, requires the `std` or `alloc` feature)
See [#1] for other primitives being considered for addition to this crate.
## Optional features
- **`std`**<br>
Use `std`.
Note:
- This implicitly enables the `alloc` feature.
- **`alloc`**<br>
Use `alloc`.
Note:
- The MSRV when this feature is enabled and the `std` feature is *not* enabled is Rust 1.36 that `alloc` crate stabilized.
